Description

Technical Field

[0001] The present invention relates to the technical field of gravity retaining wall, and more specifically, to a moving device and demoulding method of a gravity retaining wall steel mold. Background Art

[0002] Gravity retaining walls are built to prevent soil from collapsing. They are mainly wall-type structures that bear lateral soil pressure and are often used in fields such as waterways and river embankments. In order to improve on-site construction efficiency, people usually use steel molds to prefabricate gravity retaining walls, and then transport the prefabricated gravity retaining walls to the construction site for installation. When in use, they are mostly demoulded by manual knocking or pulling with external equipment, which can easily damage the steel mold, thereby reducing the turnover and service life of the steel mold. Summary of the invention

[0003] The purpose of the present invention is to provide a moving device and demoulding method for a gravity retaining wall steel mold. The device can be driven by a motor to drive the threaded rod to rotate, and the push plate can be driven to move in conjunction with the connection of the sleeve to squeeze the gravity retaining wall out of the left steel mold and the right steel mold to accelerate the demoulding process of the gravity retaining wall. During demoulding, there is no need for people to knock or drag the steel mold, thereby reducing the wear of the steel mold. The motor drive can also drive a strip-shaped knocking piece to knock the vertical rod to make the steel mold vibrate. The vibration can accelerate the demoulding process and reduce the occurrence of hollowing problems after the gravity retaining wall is cast. After the motor drive, the water in the square tube can be squeezed into the steel mold to lubricate the space between the steel mold and the gravity retaining wall, thereby further accelerating the demoulding.

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and implementations, and its specific implementation process is as follows: like Figures 1 to 3As shown, the present invention provides a moving device for a gravity retaining wall steel mold, comprising: a left steel mold (1), a right steel mold (11), and a gravity retaining wall (12) cast between the left steel mold (1) and the right steel mold (11), wherein the left steel mold (1) and the right steel mold (11) are provided with a pressing mechanism for pressing and demoulding the gravity retaining wall (12), wherein the pressing mechanism comprises a plurality of sleeves (2) fixedly arranged on the outer walls of the left steel mold (1) and the right steel mold (11), a threaded rod (21) threadedly arranged in the sleeves (2), and a threaded rod (21) fixedly arranged at one end of the threaded rod (21) and located between the left steel mold (1) and the right steel mold (11).

A knocking mechanism driven by the motor (3) for vibrating the left steel mold (1) and the right steel mold (11) is provided on the outside of the left steel mold (1) and the right steel mold (11). A water injection mechanism is provided on the outside of the left steel mold (1) and the right steel mold (11) for injecting water into the steel mold for lubrication after the threaded rod (21) moves. In this embodiment, a lifting lug (not shown) for facilitating lifting and moving can be provided on the outside of the steel mold, and the steel mold can be composed of a left steel mold and a right steel mold, or can be composed of a plurality of steel molds, which are not limited in this regard.

[0019] The technical solution may also include the following technical details to better achieve the technical effect: a plurality of fixing frames (31) are fixedly provided on the outer walls of the left steel mold (1) and the right steel mold (11), and the motor (3) is fixedly provided on the inner side of the fixing frame (31).

[0020] The technical solution may also include the following technical details to better achieve the technical effect: the connection mechanism includes a fixed sleeve rod (32) fixedly arranged at the output end of the motor (3), and a square rod (33) slidably arranged in the matching fixed sleeve rod (32), one end of the square rod (33) is plugged into a square hole provided in the threaded rod (21), and a spring (34) is fixedly arranged in the fixed sleeve rod (32) for pushing the square rod (33) toward the threaded rod (21).

[0021] The technical solution may also include the following technical details to better achieve the technical effect: the knocking mechanism includes a plurality of vertical rods (4) fixedly arranged on the outer walls of the left steel mold (1) and the right steel mold (11), and a strip-shaped knocking member (41) fixedly arranged on the outer wall of the fixed sleeve rod (32) for knocking the vertical rods (4) after rotation, wherein the strip-shaped knocking member (41) is a long strip-shaped object such as an iron chain that can knock an object to cause the object to vibrate.

[0022] The technical solution may also include the following technical details to better achieve the technical effect: a receiving groove (12) for receiving the push plate (22) is provided inside the left steel mold (1) and the right steel mold (11); the water injection mechanism comprises a square tube (5) fixedly arranged outside the left steel mold (1) and the right steel mold (11), a square plate (51) slidably arranged at one end of the square tube (5), and a water injection pipe fixedly arranged in the square tube (5) for adding water; the threaded rod (21) is rotatably arranged in the square plate (51); a top ring (52) is fixedly arranged on the outer wall of one end of the threaded rod (21) for pressing the square plate (51) toward the sleeve (2) side during demoulding; and a water guide pipe (53) is provided in the left steel mold (1) and the right steel mold (11) for sending water in the square tube into the receiving groove (12) during demoulding.

[0023] The technical solution may also include the following technical details to better achieve the technical effect: a corrugated tube (54) for covering the column threaded rod (21) to prevent water is fixedly provided between the sleeve (2) and the square plate (51), and an air guide hole communicating with the inside of the corrugated tube (54) is provided on the outside of the square plate (51).

[0024] The present invention also provides a demoulding method using a moving device of a gravity retaining wall steel mold, comprising the following steps: The motor (3) is started to drive the threaded rod (21) to rotate through the connection mechanism, and the threaded connection of the sleeve (2) to the threaded rod (21) can drive the push plate (22) to rotate and move at the same time, so that the push plate applies a thrust to the auxiliary gravity retaining wall, thereby accelerating the demoulding process of the gravity retaining wall (12). When demoulding, there is no need for people to knock or drag the steel mold, thereby reducing the wear of the steel mold; The threaded rod (21) is threadedly rotated to move toward the gravity retaining wall side, driving the top ring (52) to squeeze the square plate (51), so that the square plate (51) moves toward the sleeve (2) side, and the water in the square tube (5) is pressed into the receiving groove (12) through the water guide pipe (53). Since the push plate (22) will slowly leave the receiving groove (12) during demoulding, the water can flow into the left steel mold (1) and the right steel mold (11) through the receiving groove (12) to lubricate the steel mold and the gravity retaining wall, thereby accelerating demoulding. The water in the square tube 5 can be ordinary tap water or a demoulding liquid specially used for demoulding. The bellows 54 can cover the threaded rod 21 to prevent the water in the square tube 5 from contacting the threaded rod 21 for a long time, thereby preventing the threaded rod 21 from rusting and being difficult to rotate.

[0025] The technical solution may also include the following technical details to better achieve the technical effect: when the motor is started, it will drive the fixed sleeve rod (32) to rotate, thereby driving the strip-shaped knocking piece (41) to rotate accordingly, so that the rotated strip-shaped knocking piece (41) can knock the vertical rod (4) horizontally. For details, please refer to the attached Figure 3 .

[0026] In the above technical solution, after the motor is started, it drives the strip-shaped knocking piece 41 to rotate to knock the vertical rod 4, causing the steel mold to vibrate. The vibration can accelerate the demolding process. After the gravity retaining wall 12 is poured, people completely move the square rod 33 into the fixed sleeve rod 32 to disengage the square rod 33 from the square hole of the threaded rod 21, so that the threaded rod 21 is disengaged from the motor 3. The vibration generated by the knocking after the knocking mechanism rotates can make the bubbles in the concrete float up under the vibration, thereby reducing the bubbles inside the concrete (similar to the principle of a concrete vibrator), and further reducing the occurrence of hollowing problems after the gravity retaining wall is poured.

[0027] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the embodiments shown and described herein.
